fittings for the fixingror attaching ,oluarticles known as skinsorsubstitute thereof, to skis.

This invention involves a simple. manner of attachmenhby providing atleast one group of and the other part with the ski. These elements bybeing .properly joined are capable of consti tuting a composite,securely connected whole; the elementsintegral-with the ski notextending beyond'thesole or. plane of the lower resting face of thelatter.

The annexed drawing illustrates some embodiments of the invention givenby Way of examples. Figs. land 2 are an upper viewand a side View of theski supplied with a skin fixed by the means of fittings according totheinvention; Figs. 3 and 4 are an underneath view from below andcorresponding cross section showing afirst embodi ment of a groupof'elements; Figs. 5 and 6 are cross sections similar to that of Fig. 4but concerning variations;- Figs. '7 and 8 illustrate two embodiments cl3. fitting device belonging to a group'of elements, this device beingintended to be placed in a longitudinal groove of the sole of the ski.

The ski of Figs. 1 and 2 is made of the wood l and of aretaining device2. ,It is provided with a skin 3 stretched by means of fittings 4, itsfront extremity being fixed to the wood by a buckle 5 enclosing the tipof the ski, To increase the ad hesion of the skin to the ski,"the skincan be stuck to the latter by means of a paste independently of thefittings forming the features of the present invention. The groups ofelements forming the fittings are three in number in the example shownand are to be found at 6, l and 3. At these same places, aswillpresently be seen, the skin is rendered mechanically adherent to theski. It is to be noticed at one of these places, that one member of agroup of elements I is placed in the region of the ski to be found imoutof the lower surface of the wood as in the I case of every ski. In thisgroove is placed an anchoring member iii having the main form of ahooklike a U, but Whose length at the middle part should be relativelygreat, for example, a

multiple of the length of the branches. Fig. 7

In Switzerland illustrates such. a member of" which the I middle part His effectively very long compareditozthe length of the prongslZ.Besides, to the skin is fixed a small metallic plate 13 the centre ofwhich is cut out and bent back in order toform catches it of which thejaws'are directedthe one against the other and-enclose'tightlythe'middle part oi=the hooked U-shaped 'member ill. The fixing of thesmall plate to the skin is accomplished by meansof rivets 15.

As can be seen member it does not project be of interfering with theproper gliding of the ski.

The connection of this member with the catch [4 is also effected in saidgroove 9. The setting in place and making of the connection or evendisconnecting is effected in a very simple manner. To do this it issufiicient to apply the part of the skin 3, to which is fixed the smallplate l3, against the wood immediately at the sides of member II] forexample, and above this member as in Fig. 3, and to accomplish theconnectionby sliding in the direction of arrow 16. The operation ofdisconnecting is then'done by slidingin the opposite direction, therelative moving of the'parts to be connected being lengthwise.

To permit this jointing of the elements of a group it is clearlynecessary that the hooked U- shaped member ll] orll, for example such asrepresented at Fig. 7, should be laterally notched at ll, that is to.say at the point where the middle part and the two branches are joinedthe one to the others.

Instead of notching laterally the hooked U- shaped member, it ispossible to give to the middle part of the latter a trapezoidalcross-section as represented in thesection-view of Fig. 5 at l8. Thepart of this member emerging-from the wood then constitutes a dove-tailwith which the catches of the small plate I3 can engage.

Instead-of forming the catches of said small plate by cutting upfollowed by folding back, it is equally possible to resort merely to afolding back, in giving for example to the small plate the shape shownin the side-view at E9 on Fig. 6. In that figure the said plate isrepresentedas separated from ski l and from anchoring member illenabling one to see thatit presents normally a convexed shape theconcavity of which is turned towards the ski. This shape offers theadvantage of securing a better application of the plate and consequentlyalso of the skin against the ski, the setting in place requiring acertain amount of pressure to deform the plate and to flatten it againstthe wood. The elasticity it presents also makes it possible to take upon the wear of the lower face of the ski against which the edge of theWings of the plate will always rest correctly.

Finally, instead of utilising an anchor member presenting in the mainform of a U-shaped hook, one could utilise a similar member such asrepresented in Fig. 8 and showing several prongs 20, 2|, 22 allowing thesame to be fixed in the wood. The middle part 23 can likewise beextended from one or the other of the extreme prongs 2D and 22 and endin a whistle shape as shown at 24, for the purpose of diminishing theresistance it could offer to the sliding.

Manifestly variations other than those shown may be resorted to andparts or features used without others within the scope of the appendedclaims.

Having now fully described our invention, we claim:

1. In fittings for fixing and the like to skis and comprising at leastone pair of cooperating members capable of securely connecting the skiand skin into a composite whole, wherein the one or first member isfixed to the bottom of the ski and the other or second member secured tothe skin, the features consisting in that the first member fixed to theski is elongated longitudinally of said ski and has prongs at the endsextending into the bottom of the ski, there being longitudinallydisposed notches formed in said ends and prongs at their mutualjunctions, and in that the second member secured to the skin includes anintegral pair of opposed elongated jaws capable of partly enveloping anddirectly gripping the elongated portion of said first member inlongitudinally slidable relation therewith.

2. Fittings for skis according to claim 1, wherein the first orelongated member is located in a longitudinal groove in the bottom ofthe ski, and the jaws of the second member project into said groove whensaid jaws grip the first member.

3. Fittings for skis according to claim 1, wherein the first member islocated in a longitudinal groove in the bottom of the ski, and thesecond member is actually subdivided into two individual membersextending toward each other and each 01' said individual membersconstituting a jaw, and wherein both jaws project into said groove whensaid jaws engage the first member.

4. Fittings for skis according to claim 1, wherein the cross section ofthe elongated portion of the first members is substantially round, sothat ie same can be directly gripped by the jaws of the second member.
